13 Claims.

."This invention relates to nozzle spray regulators and particularly to certain improvements on the structure shown by Patent 1,767,161, issued June 24, 1930, to T. J. -Weaver.

An object of the invention is to provide a simpler type of spray regulator than that disclosed by said Weaver patent and to further simplify the Weaver device as regards mounting of the regulator on a stake carried by the nozzle Another object is to adjustablypivot a spray regulator on a stake carried by a nozzle, and to adapt such regulator to be securely retained in selective positions of, adjustment.

A further object is to provide spring means resisting accidental shiftingof a pivotal spray regulator from a selected angular position thereof, suchmeans yielding when the regulator is manipulated to change its adjustment.

A further object is to pivot a spray regulator on a spring element applying a stress serving to is increased in width, as indicated. at 6 and hold the regulator definitely adjusted while affording its manipulation to change the adjust- 'ment. 1 I

A further object is to pivotally mount a nozzle spray'regulator on a spring element engaging one edge of a stake carried by the nozzle, and to further .utilize thespring element to yieldably hold the regulator engaged with a serrated 'opposite edge of thestake. Y

These and various other objects the invention attains by. the construction: hereinafter described I and illustrated in the accompanying drawing, wherein: a

In these views, the referencebhartrctei"! des ignates a nozzle having an'inlet'2 threaded for connection with a garden-hose indicated at 3,

and having a relatively small outlet A coaxial with thefinlet. Rigidly connected to the nozzle and preferably integral therewith, is a stake 3 pointed at its free end so that it maybe readily pressed into the ground to support thenozzle in a desired position, Preferably said stake has a Width materially exceeding its thicknessthe approximate plane determined by its width and length being such as to include the nozzle axis.

The portion of the stake adjoiningthe nozzle passes through a-slot 1" formed in the mid portion ofja spray regulator 8. 'Forwardly of'said midportion the spray regulator comprisesa defiecting plate 9 having a substantially semi-circular free end, and rearwardly of said portion the regulator has a downward inclination and flares rearwardly to an increased widtha'sindicated at 10. j

Describing now the pivotable support for the spray regulator, a spring 'll formed of strip sheet metal extends through the slot 7 bet-ween spaced upper and lower shoulders l2 and 13 formed on the front edge of the stake 5, said spring being bowed to clear said edge between said'shoulders'and the, spring width being substantially equal to the thickness of they stake. The upper of said shoulders is in close proximity 'to the outlet end of the nozzle, so that the latter front edge of the slot 1. The rear edge oi said slot is rounded to form a tooth selectively err gageable in any of a series of shallow pockets l8 *formed by'srratin'g the rear edge of the;relatively wide upper portion 6 of the stake, such serrated 'edge forming an approximate arc centered at the 'pivot' pointof thejspray regulator.

This arrangement subjects the spring I! to a. constant slight-distortion;tending to maintain any selected engaged relation ofthe spray regul'ato'r'with the serrated edge andhence resisting g 'angularshifting of the regul'at'or.

of the stake and engaged in one of the pockets 16 of such edge.

In the modified construction shown in Figs. 6 and '7, there is provided a nozzle la with threaded inlet 2a and relatively small outlet [a coaxial with the inlet. A stake 5a is rigidly carried by a maximum range. When desired, the stake 5, 5a or 5b may be used as a handle for the nozzle, the finger-piece H) or [0a being then readily operable by the thumb of the hand gripping said stake.

The entire device, in its various modified forms, is quite inexpensive and lends itself to production of the parts as die castings.

What I claim is:

1. A spray device comprising a nozzle having a discharge port, a member connected to and projecting from the nozzle, a spray regulator having a deflector exterior to the nozzle, said regulator being pivoted on said projecting member to afiord angular movement of the deflector across the extended axis of the discharge port, a spring the nozzle and has its upper portion widened, as

indicated at 6a. Such widened portion is accommodated within a slot la of a spray regulator 8a and the forward portion of the latter forms a deflecting plate 9a, the modification fully conforming as so far discussed to the firstdescribed construction. From the front edge of the slot -la there projects integrally a pivot member a for the spray regulator, and the front edge of the stake 5a is formed with a notch [9 to accommodate such pivot member. Extending from the rear end of the slot 5a to the rear end of the regulator 8a is a bore having its rear portion Compressed bethreaded to retain a screw 20. tween such screw and a pin 2| slidable in said bore is a coiled spring 22 urging the rounded front end of the pin against the rear edge of the portion 6a. of the stake, such edge 16a being serrated t and forming an approximate arc centered at the pivot of the regulator. Thus the spring-pressed pin serves as a detent to yieldably maintain adforming a pivot bearing for the regulator and reacting between the regulator and said projecting member, and means on the projecting mem- .ber correlated with the regulator to yieldably resist pivotal movement of the regulator, responsive to said spring reaction.

2. A spray device comprising a nozzle having a discharge port, a spray regulator having a deflectorand movable to intersect the deflector with the extended axis of'said port at selective angles, a spring carried by the spray device and pivotally mounting the regulator to afford said angular movement of'the deflector and means in engagementwith the regulator resisting its pivotal movement, said spring yieldably urging the regulator into such engagement.

3. A spray device comprising a nozzle having a discharge port, a stake carried by the nozzle at an angle to the axis of the discharge port, a spray regulator having a slot to accommodate said .stake and having a deflector, a spring pivotally justment of the regulator, serving substantially the'purpose of the spring I l in the first-described construction. The finger-piece function of the rear portion lOa of the regulator is retained in the modification, in adapting such portion to mount the spring-pressed pin. y

In the further modification shown by Figs. 8 and 9, the parts lb, 217, 4b, and 5b are substantially like the parts I, 2, 4 and 5 first described. The spray regulator comprises a deflecting plate 927 and a pair of parallel arms 23 integral with and rearwardly projecting from said plate and straddling the widened upper portion 6b of the take. Said arms are formed with aligned apertures and these are further aligned with a tapped aperture in the portion. 61) to accommodate a screw 24 serving to pivot the spray regulator on the stake. Said screw has a wing head 25 or Ill other suitable provision for clamping at least one of the arms 23 against the stake to hold the spray regulator selectively angularly adjusted.

In each of the described modifications it will be noted that the pivotal mounting of the spray regulator permits the deflecting plate (or deflector) thereof 'to intersect the axis of thenozzle outlet in selective angular relations to,such axis,

and in each case provision is made. formaintaining any adjustment of thespray regulator, while permitting it to yield when manipulated.

When a jet of water-discharging from the nozzle encounters the deflecting plate, it fans out to an extent determined by divergency of such plate to the jet and hence the resulting spray may be applied to a large or smallarealas" may 7 be desired. By adjusting the deflecting plate to its lowermost position, it may be withdrawn from contact with the jet, so that the latter may have mounting the regulator and thereby affording the deflector anangular movement across the extended axis of the nozzle and alsoa movement for restraining purposes, said spring reacting between the stake and an edge of said slot, to exert restraining pressure on the regulator, and means on the stake, and engaged by the regulator under pressure imposed by said spring to normally restrain the regulator for said angular movement.

4. A spray device comprising a nozzle having a discharge port, a member connected to and projecting from the nozzle and having a serrated edge, a spray regulator formed with a slot at:- commodating said projecting member and formed with a deflector, means pivoting the regulator at one end of said slot on said projecting member whereby the deflector may intersect the extended axis of the nozzle at selective angles to such axis, and means on the regulator at the other end of said slot coactingwith said serrated edge to hold the regulator selectively adjusted.

5. In a spray device as set forth in claim 4, a spring reacting between said projecting memher and the regulator to hold the regulator selectively adjusted.

6. A spray device comprising a nozzle having a discharge port, a member connected to and projecting from the nozzle, a spray regulator having a deflector, means pivoting the regulator on the projecting member to afford the deflector selective angular. positions of intersection with the extended axis of said discharge port, said projecting member having a serrated edge in substantially the form of an. arc centered at thepivotal axis of the regulator, and a springspressed detent on the regulator engageable with said serrated edgeto holdthe regulator selectively pivotally adjusted.

7. A spray device comprising a nozzle, an elongated supporting member for thenozzle connected to and projecting from the'nozzle, a spray notched to receive projections on the other memher, and means interengaging'said members un-' regulating member including a deflector, one of said members having a portion formed with a serrated edge and the other member having a slot accommodating said serrated portion, means pivoting the regulating member at one end of said slot on the supporting member, whereby the deflector may be adjusted to intersect the ex-] tended nozzle axis at selective angles to such axis, and means on the slotted member at the other end of said slot coacting with said serrated edge to hold the regulating member in a selective, pivotal adjustment.

8. A spray device comprising a nozzle, an elongated supporting member for the nozzle connected to and projecting from the nozzle, a spray regulating member pivoted on the supporting member and including a deflector, one of said members having a slot accommodating the other member, a spring at oneend of said slot react-v ing between the two members to exert pressure on the regulating member, and an element at the other end of said slotengagedby the regulating member under pressure imposed by said spring I and restraining the regulating member from accidental pivotal movement.
